You are healthy, cancer free, count your blessing.
We have come a long way actually. I am a cancer surviver because of research that found effective treatments for my type. Many other cancers can also be cured but lung, brain and pancreatic are still a death sentence. Lung cancer is a tough nut to crack, like stock charts, no two are exactly alike.
If you read, you will find that it is heterogenous, there are countless different mutations and they are often countless combination of different cancer cells within the cancer. In my wife's lung cancer, I searched through all medical journals, research articles..., only found one patient with her particular mutation, an oncogene! That make treating it extremely challenging. It has no cure.
Like day trading, there are perhaps some rules or general strategies that can be use as guides. One of which is using our body's own immune system to fight all of the variance. That is why mRNA has some promise and surprisingly why ivermectin may have benefit because it turns out ivermectin affects our body's immune system, just like mRNA vaccines.
I made tons trading biotech options but would gladly give them up for a couple of years.
Best wishes.
